IMPROVEMENT IN PUTTING UP ALKAIIH-ISI TO ALL WHOM IT MAY CONCERN: I

Be it known that I, J onn Rnsxmr, of Philadelphia,-county of Philadelphia, and State of Pennsylvania, have invented certain new and useful' Improvements in Putting up Caustic Alkalies; andI do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ahcompanying drawing, and the letters of reference marked thereon, making part of this specification, in which-- Figure 1 is a sectional view bf the jar, with thedisk removed. j l

Figure 2 is a sectional view of the jar with the disk in place, and cemented. The stone or earthenware id shown in brown; the glazing in blue, the disk in yellow, and the cement in red. s

Figure 3 is a view of the jar or case packed and ready for market.

The nature of my invention consists in so glazing the inner surface of an earthenware or stone jar crease, having near its opening a shoulder or flange, so arranged asto formn support for a disk or plate, that when the jar or case is united together, through the agency of the cement hereinafter alluded to, a cheap, safe; and secure vessel is formed, that will enable the manufacturer of caustic alkalies to put them up in small and convenient packages for'family purposes. Practical experience has fully demonstrated the fact that the caustic alkalies packed in 'jars or'cases'similar to mine, and securely sealed with thecement used by me, can be preserved in-all their original purity for any given length of time. The inner glazing of the jar or case, and the under surface of thedisk or plate, I have found to be indispeusably necessary, in order to render the vessel entirely impervious to the action of the alkalies, and at the same time entirely guard the .sauieftom the deleteriousefiects of atmospheric contact. i

Ihave also, in my various experiments, discovered that great care has to be taken in the selection of the cement used. The one that I have found admirably adapted to the purpose is composed of the following ingre: di ents: Bees-wax, rosin, powdered brick, and pure German Burgundy pitch. The last is far superior to the ordinary pitch found in the market, and the well-known product of the southern States, as it possesses a degree of elasticity, a feature most desirable in the present use, not met with in the American pitch.

To enable-others skilled in the art to make and use-my invention, I will now proceed to describe its con struction and operation. I i

A is a. jar or case, made of stone or earthenware, and provided with ashouldcr or .flange, a. This jar or case A may be circular or square in form. V I

p B is a disk or plate, of the same material, and rests on the shoulders or flange a. The diameter of the disk B is.a little less than that of the mouth of the jar or case A, and its thickness about one-sixteenth of an inch iessthan is the distance between the shoulder or flange fund the upper surface of the jar or case A. The spaces left between the surface of the case and the rim of the disk, and also between the upper face of the disk and the top or ridge of the case, are most essentially necessary to the successof my. invention, for when the alkaliesare placed within the vessel, and the disk B properly adjusted on'the shoulders a, the cement, being poured on in a soft or plastic state, will run down betweenthe jar and disk, firmly securing the same together,

and at the same time, without projecting at all above the upper surface of the vessel, entirely coat the face of. the disk, thus literally embedding the same in the cement.

The entire inner surface of the jar and under face of thcdisk are glazed by any of the well-known processes now used by potters and other manufactiii'ers, as clearly shown in blue in figs. 1 and? I fill the vessel A with the alkalies, in amelted state, iipreferred, or, before being placed in the vessel, the alkalies may' be pouredinto moulds, and allowed to cool; and then, being formed in suitable blocks, placed iuthe jar or case. The disk 13 is then placed on the shoulders 11, and a cement, in a plastic 'state,composed of bees-wax, rosin, 'GermauBungundy pitch, and powdered brick, is poured on the disk B, until the spaces between the disk and the vessel are all filled, and the face of the disk coated with the solution to a depth equal to the distance between thesame and the upper surface of the jar, when the cement is allowed towel, and the alkali is ready for market, in packages similar to thatshbwn in fig. 3. The manner in which the cement surrounds the top and sidesof the disk is clearly shown in red in fig. 2.

. Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent of the United States, is-

Packing caustic alkelies in a glazed jar or case, A, having a. shoulder or flange, a, to support the disk or plate B, when the whole is hermetically sealed. with the cement herein named,' substantially as described; and for the purpose specified. I

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN REAKIRT.
